Tips and tricks for reef tank photography

[Albertan22]

I think what this site is lacking is a good thread on how to take good reef tank shots! I know there's information scattered throughout dozens of threads on the site, but maybe if we congregate it here in this thread it will get posted into the tips and tricks forum or sticky'd. Please post any advice you can give on how to take those great eye candy tank shots This could include techniques, camera settings, SLR lenses (if applicable), that special way you need to hold your tongue, etc.

Unfortunately I haven't mastered the art yet, but I can offer the following:
-manually set your white balance so your colours are more accurate
-close curtains and darken the room so you don't get reflections
-clean your glass a few hours before taking pictures to let everything you've kicked up in the water column settle
